The first one was with the pairings Clint Barton/Phil Coulson/Natasha Romanov. Phil turned out to be alive after the battle, and when Clint went through the window Ethan Hunt was there (I think it was the IMF building he was clearing out) It was a crossover with some of Jeremy's movies and he was those characters undercover. Clint Barton/Phil Coulson/Natasha Romanov ended up letting Ethan be with Clint. And I think at the end Clint and Tony were going to go to L.A. to Clint's old undercover work. I think it also had Steve/Pepper/Tony towards the end, but I could be wrong.
The second one is where the headquarters were taken over and everyone were in cells. And it's up to Clint to get headquarters back and save everyone. Or anything where Clint shows Shield how badass he can be and saving them or some of them, especially if they blame him for what Loki did to him. Bonus if Phil is alive. Agents of Shield crossovers are welcome.
I'll take stories with Clint Barton/Phil Coulson or Clint Barton/Natasha Romanov.
